A video recording device includes an image capturing module, a storage unit and a processing unit. The image capturing module is configured to capture a raw video in a first video format. The processing unit is configured to convert video session(s) other than the lately captured video content from the first video format into a second video format. The second video format is inferior than the first video format.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A video recording device, comprising: a storage unit having a plurality of storage spaces; an image capturing module configured to capture a raw video in a first video format, wherein the raw video includes at least two video sessions; and a processing unit connected to the storage unit and the image capturing module, wherein the processing unit is configured to: determine whether a trigger signal is received; when the trigger signal is not received, automatically convert a first video session captured before a preservation window from the first video format into a second video format, while preserve a second video session within the preservation window in the first video format; and when the trigger signal is received, preserve a relevant video session of the raw video in the first video format, wherein the relevant video session includes a video session recorded immediately before the receipt of the trigger signal, a video session immediately after the receipt of the trigger signal, or the combination of the above; wherein the first video format is of a higher quality than the second video format.
2. The video recording device of claim 1 , wherein a length of the second video session within the preservation window includes the last video contents of the raw video.
3. The video recording device of claim 1 , wherein the processing unit is further configured to control the storage unit to store the raw video and the second video session in one storage space, and configured to store the converted video session in another storage space.
4. The video recording device of claim 1 , further comprising an input interface connected to the processing unit, wherein the input interface is configured to generate the trigger signal when a user commands through the input interface.
5. The video recording device of claim 1 , further comprising a sensing unit configured to detect a collision and generate the trigger signal accordingly.
6. A method of recording and storing a video, comprising: capturing, by an image capturing module, a raw video in a first video format, wherein the raw video includes at least two video sessions; and determining, by the processing unit, whether a trigger signal is received; when the trigger signal is not received, automatically converting, by a processing unit, one or more video sessions other than a video session within a preservation window from the first video format into a second video format, while preserve the video session within the preservation window of the raw video in the first video format; and when the trigger signal is received, preserving, by the processing unit, a relevant video session of the raw video in the first video format, wherein the relevant video session includes a video session recorded immediately before the receipt of the trigger signal, a video session immediately after the receipt of the trigger signal, or the combination of the above; wherein the first video format is superior than the second video format.
7. The method of claim 6 , wherein a length of the video session within the preservation window includes the last video contents of the raw video.
8. The method of claim 6 , further comprising: controlling, by the processing unit, the storage unit to store the video session within the preservation window and the converted video sessions in separate spaces of the storage unit.
9. The method of claim 6 , further comprising: generating, by an input interface, the trigger signal when a user commands through the input interface.
10. The method of claim 6 , further comprising: generating, by a sensing unit, the trigger signal when a collision is detected.
11. A non-transitory machine-readable storage medium including instructions, which performed by one or more processors, causing the one or more processors to perform a method of recording and storing a video, the method comprising: capturing a raw video in a first video format, wherein the raw video includes at least two video sessions; determining whether a trigger signal is received; when the trigger signal is not received, automatically converting one or more video sessions other than a video session within a preservation window from the first video format into a second video format, while preserving the video session within the preservation window of the raw video in the first video format; and when the trigger signal is received, preserving a relevant video session of the raw video in the first video format, wherein the relevant video session includes a video session immediately before the receipt of the trigger signal, a video session immediately after the receipt of the trigger signal, or the combination of the two; wherein the first video format is of a higher quality than the second video format.
12. The medium of claim 11 , further comprising: determining a length of the video session within the preservation window covering the last video contents of the raw video.
13. The medium of claim 11 , further comprising: generating the trigger signal when a user commands so.
14. The medium of claim 11 , further comprising: generating the trigger signal when a collision is detected.
